To aIZZ whom it may -cortccrnf` Be it known that I, MONTGOMERY WAD-DELL, of New York, inthe county vofy New yYork and State of New York,have invented certain new and useful Improvements in A paratus forForming Filaments, whereof t e 'In the drawings, Figure I represents a'View, partly in longitudinal section through thevspinning-trough andpartly in side elevation of the spinning-tube and its standard, of anapparatus embodying my invention in one of its simpler forms where onlya single trough is employed. Fig.V II is an enlarged verticallongitudinal section through the s inning-tube and standard, showin insection the adjacent end ofthe trouv' III is a transverse section throuh tbe stan ard on the line III III of Fig. Il? Fig. IV is a fra mentaryvertical section taken on the line IV of Fig. II. Fig. V is alongitudinal section through the spinning-troughs, in

an amplified form, of apparatus where two` troughs re employed, certainfeatures, how.- ever being equally applicable in the case of a singfetrough. Fig. l I is a plan View of the ost of the features ofimprovement relate to anapparatus in which the spinneret is rotated asit delivers the viscose to the coagulating or so-called settingjsolution in order to twist the individual filaments spil-'ally togetheras they pass` through the settingbath and are coiled 'uponthe windingspool or roller. n .e

Referring to thejsimple type shown in Fi s.

I and II of the drawings, 1 'represents t e' trough adapted to containthe setting solution, said trough being preferably provided with adrip-box 2 at the end adjacent to the spinning device 3, in which anyescaping viscose can be' received when the-spinneret is turnedout of itsoperative position. The

`spinningdevices comprises-an elongatedtube 4, adapted to be projectedin an inclined position .into one end of the spinning-trou h, saidtubevha'ving an enlarged forward or ischarge end5, upon which thespinneret 6 containing numerouslfine orifices, is secure by means of ascrew-cap 7.. The tube 4 has secured to it a pulley 10 and is rotativelymounted'in bearings 8 9, which are respectivelyr supported by arms 11and 12, which converge to a vertical standard 13. This standard 13,which constitutes both the 'sup. port for the spinning-tube andthe ductfor supplying viscose thereto, is secured at its lower extremity to ahorizontal base-piece 14, which is pivotally mounted at 15 uponl f thebracket 16. Both the base-piece 14 and the standard 13 `are hollow, thestandard being of flattened cross-section, as indicated in Fig. III. Thechannel 17 in the base-piece 14 leads to a vertical channel 18 in thelower portion of the standard .13; but at a short distance from thelower end thereof the channel has a ltransverse ofi' set leading to anclon-.

gated vertical channel -19, which' extends near the top ofthe standard13. This chan-l nel 19 has a fiat and relatively wide cross-section, asshown in the sectional view of Fig. III, so as to afford an extendedinterior surface. nel 19 a second lateral offset leads to the channel20, `which continues upwardly `through the. arm 11 to. an annular duct22,

formed in the bearings g8 and surrounding the exterior' of the Spinnin-tube 4. An orifice 23 is formed in said tu e at the region surroundedby the duct, so that the interior of the tube is in constantcommunication wit the annular channel 22.

At the upper extremity of the chan# A' iiltering-diaphra m 21 of anymaterial i ordinarily employed or the filtration of -vis-- cose orsimilar substances is arranged vertically Within the elongated flatchannel 19 of filtration, thus permitting the travelof the.

viscose through the 4filtering-diaphragm Without requiring excessivepressure. A Web 24, .which unites the standard 13 and horizontalbase-piece 14, affords bearing for the flanged pulley 25, having a bandwhich drives thepulley 10. The shaft of said pulley 25 is actuated bymeans of a friction pulley 26, which in -turn is driven from -the maindrivingpulley 27. (See Fig. I.) The Winding IOO roller or spool 28,mounted above the settingtrough, is driven by means of a pulley 29fromaxis ofoscillatory movement of thestandard 13 and its base-piece14.`

The details of the connections are shown in vertical section in'Fig. IV.The bracket Y16.

provided with a deep vertical slot 40, the wall 41 ofwhich at one sideaffords bearing for a set-screw 42. The opposite Wall 43 is perforatedwith a channel 44, whose end adj acent to the slot is coned, as shown at45. The other end of said channel is provided with a screw-threadedconnection to receive Athe supply-tube 46;leadin from the reservoir ofviscose. At the end o the base-piece-14 is a cylindrical plug 47, havinga coned end 48, adapted to fit' snugly and move freely in thecorrespondingly-coned orifice 45. An axial channel 49 is formed in theconed end of the plug and extends upward to a point somewhat beyond thelongitudinal center thereof, where it communicates with the channel 17of the base-piece 14. The width of the slot 40 is such as to permit theplug 47 to be inserted therein and then slipped laterally intopositionin. the coned or eing held in place by means of the set-screw42. The arran ement ermits the standard to be tilted bac into t eposition indicated by the dotted lines in Fig. I, and when'thus tiltedordrawn back the nozzle will be vertically above the'drip-box 2, whileof course the friction-disk by which the pulley 25 is driven will beremoved from contact with its driving-disk 26, so that the spinning-tubewill cease to revolve. In the instance shown the necessary friction isafforded by the weight ofthe spinning-tube and its standard, butobviously modifications of this method may be empleyed. The viscosesupplied through the base-piece and standard` after being filteredthrough the diaphragm 21 is led into the annular duct 22 and thencethrough the orifice 23 into the inclined tube 4, being finallydischarged through the spinneret 6 into thesetting-bath, where it formsa group of fibers twisted to ether,`which are led below'the surface othev bath through the surface of the guide-fingers 31 to the take-uspool 28. The spool 28 is of) such diameter and so mounted with relationto the trough 1 as to at all times maintain some portion of the. take-upsurface beneath the level of the llquid in t e trough, thus continuallymoistening the Wound filament with the solutionv and protracting theaction thereof as far as ossible. This arrangement enhances uniornity.and homogeneousness A of the produc In the arrangement shown i; V and'different character from the initial setting solution in thedelivery-trou h. In this in-v insure that some portion of the peripheryIof ce 45, the parts VIit will be noted'that twospinnerets are arrangedto deliver into the same trough and also that a supplemental trough is`employed, which may containasolution of stance the filamentsare' conucted beneath .the guide-rod 39 and thence u wardthroughthe'adjustably-mounted -gui e-ngers 34 tothe periphery ofthetake-up spools 36 and 37. 'Iwo pairs of said spools are shown 1n Fig,VI, each spool being removably mounted upon the horizontal shaft 35,which is so arf ranged with reference tothe trough 50 as'to the windin-s oolshall at all timesbe below the level o t e liquid in said trough.lThe guides 34 can be turned so as to deliver filaments to either 'thespool 36 or the spool 37, and `this transfer can be made While thespools are actually running, so that as 'soon asone spool is filled 1tcan be removed independently of its fellow and an empty one substitutedin itsplace. The process of spinning and winding may thus proceedcontinuously. It will be noted that the inclined osition of thespinning-tube permits the delivery of the filaments in a directionnearly horizontal, so that they can be drawn for a relativel longdistance through the spinning-troug without abrupt change of direction.This nearl horizontal direction of travel also` afford1 filaments asthey pass to the spool. Where, as in some instancesthe filaments aredelivered vertically downward into the, Spinnin solution theseadvantages are lacking, and hence one feature of my improvements con'-`sists in the .described arrangement of the tube in an inclined positionas distm v guished from a vertical one.

Having thus claim- A 1. Thel combination of a rotatable spinning-tubeand spinneret; an oscillatory standard therefor; a main spinning-trough;and a drip-box adjacent to said main spinning-trough; whereby when the'standard is' oscillated to throw the spinneret out of its operativeposition, said spinneret will be su orted above said drip-box,substantia y-as set frtli.
